HELP WITH THE FOLLOWING Q'S

Series R-C Circuit steady state response to sinusoidal waveform 1. 2. Calculate the time constant, TRc of the circuit shown in Figure 1. If the function generator produces a sinusoidal waveform of 5V peak and a frequency of 10 kHz, ueny 1 a. What is the angular frequency ? b. What is the magnitude of the peak value of the current? C. What is the phase difference between the voltage and current in this circuit? Show your workout and insert your results into Table 1 below C-470 pF Function Generator f = 10KHz Figure 1 R-C Network Table 1 Time constant, TRC Angular frequency , (rad/s) Peak current, I p(A) Phase different

Explanation / Answer

1.Time constant , T = R*C=470*10^(-12)*10*10^(3)=47*10^(-7)=4.7micro sec.

2.(a) Angular frequency=2**f=2*3.14*10*10^(3)=6.28*10^(4)rad.

(b)peak value of current, I=E/R=5/(10^4)=5*10^(-4)=.5mA

(c) phase difference between voltage and current is 90 degree
